Wondering about CD drive data
Posted: May 17th, 2012, 8:13 am
Hey, i was going through ideas and was wondering about how the PS1 got data from the CD drive, and is it easy to interpret and intercept. Honestly i was going to see if i could make a slightly more advanced Anti-Copy protection mod that would simply take the data cable from the CD Drive, run that through the chip, then output it too the PS1.
This would be a NO-Solder alternative for PS1 owners, and would be able to defeat any copy protection with minimal processing, it would just need to be able to read the commands and alter the data slightly if the data matched the correct setting.
Such a setting would be
if{
SEEK(beginning of disk)
and
Read(4)
}then{
Output(SCE?)
}
then possibly have a small 2switch setting on the chip to change between the 3 regions. (A/J/E)
Just useless technology, that i was thinking about.
Although, information regarding the raw voltages and pinout of the cd drive would be valuable.
Such a device could also enable the PS1 system too utilize both PSIO(when finished) and the original CD drive, as you could run such a script to see if a CD is in the drive, and if not boot directly to PSIO.
